J/ApJ/838/122       Light curve analysis of 13 active stars       (Jetsu+, 2017)

General model for light curves of chromospherically active binary stars. Jetsu L., Henry G.W., Lehtinen J. <Astrophys. J. 838, 122 (2017)> =2017ApJ...838..122J (SIMBAD/NED BibCode)
ADC_Keywords: Stars, variable ; Ephemerides ; Photometry Keywords: techniques: photometric - methods: data analysis - stars: binary - stars: activity Abstract: We present results from light curve fits to the photometry of 13 chromospherically active stars, covering the time evolution of the rotational phase of their primary light curve minimum and the light curve amplitude. Description: The data table contains estimates of the light curve minimum phases and amplitudes retrieved by the continuous period search analysis (Lehtinen et al., 2011A&A...527A.136L, Cat. J/A+A/527/A136). The results for different stars have been labeled according to the names of the stars. File Summary:
